CER Principles and Maintenance 5

Question 1

What is the primary purpose of performing biological monitoring (e.g., spore testing) on sterilization equipment used in endoscopy units?

Accepted Answer

To verify that the sterilization cycle is achieving the intended kill of the most resistant organisms

Answer

Biological indicators containing resistant spores confirm that the sterilization process achieved sufficient lethality to kill the hardest-to-kill organisms, validating cycle efficacy.

Question 2

Which action is required when a high-level disinfectant solution reaches its maximum use life before the container is empty?

Accepted Answer

Discard the entire solution regardless of test results, because use-life limits are absolute

Answer

Use-life expiration is an absolute cutoff set by the manufacturer's validation; the solution must be discarded even if it still passes MEC testing, as other degradation products may have formed.

Question 3

Glutaraldehyde-based high-level disinfectants require special handling because:

Accepted Answer

They are toxic, irritating to skin, eyes, and respiratory tract, and require adequate ventilation and PPE

Answer

Glutaraldehyde vapors are irritating and potentially sensitizing; OSHA regulations require exposure controls, PPE, and ventilation when handling these agents.

Question 4

Which scenario represents a break in the endoscope reprocessing chain that would require immediate corrective action?

Accepted Answer

Discovering that an endoscope was stored with caps attached and channels closed after reprocessing

Answer

Storing a reprocessed scope with caps on and channels closed traps residual moisture, promoting microbial growth and compromising the maintained disinfected state.

Question 5

The Spaulding classification system guides endoscope reprocessing by categorizing devices based on:

Accepted Answer

The risk of infection associated with their intended use and the body site they contact

Answer

Spaulding's framework classifies devices as critical, semi-critical, or non-critical based on body-site contact risk, which determines the minimum required level of reprocessing.
